Figure 4.

Scaling of the collapse time. (a) Variation of the average squared radius of gyration R_g²(t) with time for different chain lengths as indicated. The solid black lines are respective fits using eq 5, and the corresponding β obtained is shown as a function of N in the inset. (b) Dependence of the collapse times τ_c extracted from the time decay of R_g² on the number of residues N. The solid line represents the behavior τ_c ∼ N^z with z = 0.5. For all the data shown in the main frames, the error bars correspond to the standard error of the mean, while in the inset, they result from the fitting exercise.
